Big Big Heat Issue

Ok so the heat is fine when im running the 2 cfls for vegging the 3 plants,but when the hps is runnning it hits 100 in teh grow room,anything to cool it down?i cannot build an exhaust anymore then what i already did,cut a hole in teh drywall into the wall and have a 4 inch inline fan blowing into a carbon filter blowing through the venting pipe.not helping the heat but the carbon filter will help the smell i hope.We built it ourselves from a big thread on here.ok so anyway to lower heat,im intrerested in anything! lol and what would happen to 3 plants under 100 degree heat?

Get a bigger fan, which you should have anyway to strengthen the plant. There are also small AC units that you could use to keep temps down. Cooling shouldn't be a problem.

Portable A/C's are pretty pricey I think. Look into a cool tube or vented hood. Your plants won't grow very fast with that much heat.

A swamp coolor would work. Have to by a Wall plug thermostat and build the swamp coolor or buy one.
Probably for that cost u could buy a Window unit...

I was thinking of getting a swamp cooler. They're cheap like 60$. I just got a portable a/c from craigslist

yeah i was looking at those portable air con units like 500 bucks.

but winter is almost here in australia so im happy.

My room never goes above 85, but if it gets up there i have 2, 1gl jugs of water in the freezer i cycle through. 1 knocks the temp down 5 degrease maybe 2 ore 3 will get you to a reasonable place?? If you do end up doing it make sure your water is ICE not ice around water they wont last long like that.

Thank you,I shall try this!!!

Its going to raise your humidity though

^^^^ true that...

thats fine the humidity is very low in there without that

Glad to help

i have 150mm inline fan i have like a 10 litre bucket at the end of the ducting with a hole cut for the ducting and i sit 2, 2 litre froaen bottles in there i alternate them through the day to keep temps down works well

found my solution,the closet with the door open a crack went from 100 to 88 last night,then the temps went from 88 to 78 during night hours and now the lights have been on 3 hours this morning and the temps havent been above 81 witht he door cracked,looks like my heat issue is solved!

LOL, well that was easy.
